blz bud -
400 HPS
Soil
biobizz grow and bloom
Temps are fine
i think airflow is adequate ...
PH Fine

Mainly - the big fan leaves started yellowing from bottom to top and eventually dying at 3 weeks in flower and im now on week 5.
and they are still slowly dying, flower time for this strain is about 9-11 weeks and at this rate ill have no (BIG) fan leaves left by week 7 or 8 !! then im worried that the leaves wher the buds are producing will start to follow suite ? i understand that leaves will naturally yellow but only towards the end of the bloom, in my head right now im thinking cal/mag ? does biobizz (grow) + (BLoom) have what cal/mag gives me ?

I water about twice a week maybe less, drainage seems fine ! although the tips of my leaves droop down as if they are over watered - i know they are not as they have showed me signs of wilted leaves in the procces of reacting to the droopy ends wich made me think it was over watered.

so id like to know if i can just leave the plant as is ? or if its best to correct ? and what with ? and preferably something easy to attain in UK .......

whats causing my plant to show signs of over-water ? (when not) - (Droopy Tips)

ill ad some photos of what im describing and also on one of my tops i have some small deficiency to wich i need a doctors advise ?

pics taken from phone not best quality...............

SORRY - From BOTTTOM to TOP -

NOT - top to bottom

image 318 is the mild deficiency to wich i dont know ?

cal-mag def. is what i'm thinking, you have rust spots on your leaves? any fungus gnats?

i dont know about funghus gnats ? i do know i have tiny lil worm like bugs in my soil that are cream in colour, i read tht they were no biggie and can help in some cases when it comes to mold, forgot what they were called ?

youcan see in the pics what the leaves look like

looks like nitrogen deficiency. switch back to veg nutes for a couple of weeks. i always run veg nutes for the first 1-2 weeks of flowering to avoid that problem then i switch over to flowering nutes. i can't tell whether your soil or soiless. if your using soil, get some dried blood at any garden store and water in a tsp of it.

thanks mandy that helps.

im using biobizz grow and bloom, shall i give her 1 to 1 ratio of both on her next feed ? seems wrong to not give her any bloom at 5 weeks ?

im using soil and perlite mix

1 to 1 ratio ??? her feed is soon ?

was about to say the same thing as mandy said lol,

yeah try and use some nitrogen nutes and you should see improvment! good luck man!

nitrogen nutes ??? im using bio bizz nutes (grow) and (Bloom) can i just give my plant a higher dose of grow with my bloom ? will that sort my N out ?

If your in soil, just sprinkle a tsp of dried blood. It's very rapidly absorbed, less than $10 for a big bag and available at any place that sells gardening supplies

im all out on dosh, i have bio bizz grow and bloom and ph up and down that is it, if dried blood is the only way to go, my plant is going to die then ?

well what i meant by nitrogen nutes is what ever food you got that gots some nitrogen in it bro

Displaying deficiencies of N/Ca and Mg.Feed them a balanced diet. No high P/K bloom foods. And there is nothing natural about yellowing near the end of bloom. Thats just forum bullshit. Plants that remain green and healthy until harvest produce the best fruit.

sorry , this is my first ever grow, is it looking any good to anyone ? buds dont seem very dense ! hope thats normal for week 5 ?

thanks for the help guys, i think im going to give her a feed of biobizz grow and a lil bloom with it, my biobizz products dont state any NPK on both bottles grow and bloom and came with no guidelines for use so its a lil confusing on the ratios and was hoping somone else knew, hopefully giving her more veg nutes will stop the leaves dying as she is getting pretty bare only 5 weeks in with a potential 5 to go :-s.
also hope giving her veg nutes 5 weeks in flower doesnt interupt my bud prouction in any way ?

top ppl for the reply
